While some of the founders did consider the 2nd amendment a protection against a tyrannical government that is no longer a realistic possibility. The fate of the Branch Davidians at Waco demonstrated that quite well. The role of the gun in today's society is as a deterrent. When that deterrent is not present it's an open invitation to lunatic mass-killers as we've seen demonstrated repeatedly. So why do we continue to cling to the horribly mistaken idea that the gun-free zone protects children? Are liberals so willing to deliberately sacrifice children on the altar of Progressivism to advance their agenda of government control?
